IMPROVEMNT IN RAILWAY-CAR SIGNALS.

Figure 3 is a side `view of the rear standard and its double crank-leverattacliment.

n `Our invention'hasfor its object the arrangement of blinds orblinkers, both in front and in rear of the signal-lights ou the top ofrailroad cars, in such manner thatthe engineer in charge of the train,as well as the engineer in charge of a following train, can always beinformed whether a car has become unconpled and is moving backward, orwhether any accident has happened by which aportion of the train hasbeen stopped. These signal-lights are so secured on checar that a steadyand uniform light is always emitted.

The nature of our invention consists in passing, ver- `,tically, throughthe body of the cara spindle, to the idowerV end of which, and beneaththe car, is firmly sc feux-ed a cog-wheel. This wheel meshes in andgears with a screw-thread, cut on the rear axle of the car. On the upperend ot' this spindle, and ontop of the car, is firmly secured acrank-wheel, kto which are attached, near its periphery, two crank-arms.The other end of these crank-arms is secured to the handle ,of theblinds that cover the stationary lights on -each side of the car. Thesearms are so arranged on the crankwheel that when one b lind'is openedthe other is closed. O'r, if preferred, `these handles may be dispensedwith and the crank-arms attached directly to thc4 blinds or blinkers.

Our invention also consists in' pivoting to the circumference ofthecrank-whcel, and ou opposite side-s of the same, two pawls. Thesepawls are so arranged that, when the car moves backward, they will catchin andlift one arm of a double crank-lever. The other arm of this doublecrank-lever works in a slot cut in a lever which is piveted to the frontof the rear standard. This slotted Ieverls so connected, with a shortVother `in thc rear of the light'c.

lever on the rear side of the standard, that, when the car movesbackward, the short lever, through its connections,vcauses the blind orblinker to bc thrown in front of the rear light; when the car is movingibrward, the blind or blinker is always in'the rear oi this light, andwill be shown to the engineer pulling the train only,

To enable others skilled in thc art to make and use our invention, wewill now proceed to describe its cnnstructicn and operation.

A is the rear axle, which has cut upon it, at or near its center, ascrew-thread, A.

B is'a spindle, passing vertically through the body'ifi of the car. Tothe lower end of this spindleis attaehed a cog-wheel, B', which meshesin and gears with the'screw-thread A. 'lo the upper cud of this spindleB is attached a crank-wheel, C. On this crankwheel, and near itsperiphery, is a pin, c, on which are pivoted two crank-arms, O O. Theother ends oi these crank-arms are secured to the handles C2 2 oi' theblinds or blinkers O3 O3, These handles C2 G2 are supported by andworkin slotted ghide-plates-el et, sccured to the top of' the car; or,if preferred, these hair. dles G2 C2 may be dispensed with, and thecrank-arms C* C I nay be secured dircctl'y'to the blinds or blinkcrs G3O3. y

The blinds or blinkers G3 CR are so formed that they pass both in frontand in rear ot' the stationary lights c'L c on the sides of the car.These lightsc" c arc sccured in proper cases, so that the lightemitted-from them shall be steady and uniform. To the circumferenceofthe crank-wheel G are pivoted, on opposite sides, two pawls, IZ rl.

F is a standard secured on the rear end 'of the ear.l

On the top of this standard is secured a third light, et

ff are two blinds or blinkers, one in front and the These blinds orbliukers are pivoted to two plates, h h, said plates being pivoted on apin, h', which passes through the top of the standard F, as clearlyshown in iig. 3.

`glhrough the top of the lower section ot the standard F passesa pin, H.fastened a short lever, It, which is connected by a wire, k', with oneof thc plates h. To the other cud of this pin Hl is fastened a slottedlever, F.

L is a double crank-lever, which h as its l'ulcrum in a suitable platefastened on the-tcp of the car; and between the standard F and thecircular plate D, through which passes the spindle B. This circularplate 1) has aslot, d', cut in it, said slot being oppesite thefulcrum'of the double crank-lever L. Oncarn-I,

l', of the double crank-lever works'in the slot of the lever F', whilethe other arm, I, extends suiliciently far over the circular plate D tobe operated upon by the pawls IZ d.

To the rear end of this. pin is or blinkerscoverim1 the side-li'htsstill` move alter-` nately vback and forth, but as soon as the pawl droaches the arm Z it `passes; under and lifts the same.` This movement,through the arm l', causes the slot ted lever F to change its' position,and, by means of' the lever-7a, causes the blind or blinker to be thrownin front of the rear light, thus giiiingwarning to the engineer' of thefollowing train, that the train ahead, or a portion of' the same, hasstopped.-

'Having thus fully described our invention,

\ What `Weelaini therein ns new, and desire to secure byLettcrs Patentof `the United States, is

1. The cog-wheel B', spindle B, crank-wheel (l, crank-arms Cl Cl, andblinds or blinkers' C G3, with or without their handles C C2, when thewhole is so arranged as to operate substantially as described.

2. 'lhe cog-wheel B', spindle B, crank-wheel C, pawls d d, doubleclank-lever L, slotted lever F', lever is, and blinds or blinkelsff,when the whole is so ar-` ranged as to opera-te substantially asdescribed.

In testimony whereof We have signed our names to this specification inthe presence of two subscribing witnesses.
